Mar 02, 2020 · Since water tube boilers have more surface area than fire tube boilers, they tend to be a bit more prone to scaling. This isn't an issue with Miura boilers, however, because we equip our boilers with meticulous monitoring systems and control devices that ensure minor water quality issues are detected and addressed long before they can impact the performance or efficiency of your boiler.

Water Treatment Requirements for Water Tube Boilers

The boiler water should be maintained at pH 11. This may require an addition of alkaline if the water is not soft. A chemical called a sludge conditioner can be added to treat the solids so that they drop out (precipitate). These treated solids then must be removed from the boiler by blowoff.
